The code shown above prints all the request headers which may lead to potential credential leak if the header includes the bearer token or basic auth. Even there is ttl for the token, it is still not a good practice to print those values in the info level.

Currently I didn't see a way to sensor the sensetive information as it is hard coded.

I will modify the log output logic here to only print the necessary information. I will submit the code later.
If you are interested, we'd be happy to review any modifications you'd like to contribute.
